If you've lost your dog supplement's scooper, aim for a volume between 1/4 and 1/2 teaspoon (tsp). Ideally, this is 3/8 tsp, but since that's an uncommon measurement, it's best to err on the side of caution and use a slightly overfilled 1/4 tsp. The supplement itself features beneficial medicinal mushrooms, packed with compounds like polysaccharides and triterpenes that research suggests can support immune function, reduce inflammation, offer antioxidant effects, and may even have anti-tumor properties. Brewer's yeast provides B vitamins and protein, while sorbic acid and mixed tocopherols act as essential preservatives. The inclusion of vegetable glycerin and natural chicken flavoring might be a point of concern for some pet owners, including myself. However, rest assured that the mushroom components are legitimate nutraceuticals meant to support health, and the other ingredients are standard, safe excipients and preservatives. Before introducing this, or any new supplement, to your dog, always consult your veterinarian, especially if your dog has existing health issues or is on medication. This ensures you get tailored advice. After starting, closely monitor your dog for any adverse reactions. While MOST animal supplements on the market are questionable, this one appears to be a good quality, human-grade option. As someone who prioritizes my dog's diet with human-grade and freeze-dried foods including Costco rotisserie chicken, organic raw purple cabbage, raw ginger root, raw turmeric root, organic carrots/celery/or spinach, organic blueberries, chicken liver, and organic pumpkin puree my goal is for him to live to 25, not 10, 12, or 16. I believe (I know) processed food significantly reduces a dog's lifespan. Many other dog supplements available on vine are, in my opinion, subpar or simply horrifying. I specifically chose this one to try, and I'm glad I did; he's had no allergies so far, and he loves it!
